GARPENTERS PLANE Application filed December 14, 1927. Serial No. 239,918.

My invention relates to improvements in planes for carpenters use and one ob ect is to provide a plane of this character in wh ch the blade may be adjusted to different 1nclinations for planinglumber and also adjusted to act as a paint scraper, the throat of the plane being adjustable to accommodate the various adjustments of the blade.

In order that the invention may b fully understood, reference. will now be had to the accompanying drawing, in which:

Fig. 1 is a longitudinal sectional view of the plane.

Fig. 2 is a plan view of the plane with the blade and its holding mechanism removed.

Fig. 3 is a broken plan view of the plane showing the adjustable throat slides and portions of their independent adjusting mecha-- nisms.

Fig. 4 is a cross section on line 44 of Fig. 2.

Fig 5 is a detail plan view of the blade and its holding mechanism.

Fig. 6 is a detail plan view of the blade with a rack and pinion for adjusting said blade longitudinally. V I r 7 Fig. 7 is a plan view of the blade supporting member with the upper plate thereof removed to show a pair of latches for securing said supporting member at diiferent 1nclinations.

Referring in detail to the difierent parts, 2 designates the plane stock which consists of a pair of longitudinal side members 4 and front and rear bridges 6 and 8, respectively,

which unite said side members 4. The bridges 6 and 8 are provided with handles 10 and 12, respectively, whereby the plane can be moved back and forth whendressing a plece The handle 10 is free to rotate but the handle 12 is fixed to the bridge 8.

The lower portion of the side members 4 have longitudinal slots 14 in which front and rear throat slides 16 and 18, respectively, are:

operably mounted for varying the width and position of the intervening throat 19. The

slide 16 is adjusted longitudinally by means of a pinion 20' and a rack 22, which latter 1s formed at one side of a slot 24 extending 5o longitudinally of said slide 16. The pinion 20 is held in the slot 24 by the bottom of the slide 16 and a removable plate 17 secured to said slide by screws 19. The pinion 20 is mounted upon a shaft 26 which is journaled in the front bridge 6 and extends vertically through the handle 10 which is in" the form of a knob and may be rotated for the purpose of adjusting the slide 16 longitudinally in either direction by rotating. the shaft 26 and through it the pinion 20. A portion of the shaft 26 is rectangular and fits snugly in a complemental opening extending through the handle. 10 to prevent the latter from rotating independently of said shaft. After the throat slide 16 has been ad- V justed to the desired point it is secured from accidental movement by a nut. 28, threaded upon the upper end of the shaft 26 and ada ted to secure the knob 10 from rotation loy forcing the latter firmly against the bridge 6. j 70. i

The rear throat slide 18 is adjusted longitudinally by mechanism similar to that employed for adjusting the slide 16, and as shown more clearly byFigs. .1 and 3, consists of a pinion 30 and a rack 32, which latter is formed at one side of a slot 84 extend-. ing longitudinally of said slide 18. The pinion 30 is mounted upon the lowereend of a'shaft 36 which is journaled' in the handle; 12 and provided at its upper end with a wheel '80 38 whereby it may be rotated for the purpose of rotating the pinion30 and thereby adjusting the. slide 18 longitudinally in either direction. After the slide 18 has been ad-. justed to the desired point it is secured from accidentalmovement by means of a stud bolt 40 and a nut 42. The stud bolt 40 is secured to the slide 18 and extends upwardly through a longitudinal slot 44 in the bridge 7 8, the upper surface ofwhich latter the nut 42 is adapted to firmly engage and thus secure the slide 18 at any point of its adjustment, as abovestated. j 3

46 designates the blade ofthe planewhich longitudinally. adj ust-able upon a support transverse pin 50 carried by. the oppositely-- disposed side members 4 of theplane stock 2. A removable wedge member 52 is secured at itslower forward portion to the supporting member 48 by a set screw 54,.which extends through longitudinal registering vslots 56 and 58 formed in the blade 46 and the wedge 52, respectively. The lower end of the set screw 54 is threaded in the supporting member 48 and provided at its upper end with a head 60 which overlaps the sides of the slot 58.

The upper rear portion of the wedge 52 is secured to a spring 62 which is frictionally 95 I ing member 48pivotally mounted upon a held in engagement with the upper portion of the blade 46 by a presser member 64, of

U-shaped cross section and having slots 66 in its opposite sides through which a pin 68 extends, said pin 68 being mounted in lugs 70 projecting upwardly from the rear portion of the wedge 52. The presser member 64 is provided with an upturned end 72 whereby it may be slid upwardly on a lever 74 to quickly release the spring 62.

The lever 74 is mounted upon the pin 68 and provided at its lower end with'a set screw 7 6 which bears at its lower end upon a knob 78 provided with a shank 79. By rotating the set screw 76 in one direction when the presser member 64 is adjusted downwardly upon the pin 68, the lower end of the lever 74 is caused to travel outwardly upon said set screw and push upwardly upon the lower end of the 'presser member 64,'thereby causing the upper end of the latter to push down wardly upon the spring-62 and cause it to coact with the set screw 54 in firmly holding I .the blade 46 inany of its longitudinally adjusted positions.

The means for adjusting the blade 46 longitudinally-is similar to that employed for adjusting the slides 16 and 18 and consists of a pinion 80 and a rack 82, which latter is formed upon oneside of the slot 56, while the pinion 80 is mounted upon the rectangular portion 84 of the shank 79.

The blade supporting member 48, together {with the blade 46, may be swung todifferent inclinations upon the pin 50 and held in any of such'positions by means of a pair ofspringactuated latches 86' which are provided with lugs 88 adapted to enter any of the associate recesses 90 in the side members 4 of the stock- 2. As shown by Fig; 7, the latches86 are normally pressed outwardly't'owardsthe assooiate recesses 90 by a spring '92 and are mounted upon pivots 94 in'cavities 96 formed in the supporting member 48, said recesses being normally covered by a plate 98, Fig. 1. As

shown by Fig. 1, the recesses 90 are arranged in'anarc struck from the pin 50, so that any of said recesses may be entered by the associate latches as the blade supporting member 48 is rocked forward or backward to change the inclination of the blade 46.

From the foregoing description taken in connection with the drawingit will be understood that the blade 46 may be adjusted longitudinally tobring it into proper rela-' by engaging the latches 86 in any of the re? cesses 90 and also adjusted to act as a scraper and secured in such position by means of the latches 86 and the recesses 90. It will be further understood that the width of the throat 19 can be vari'ed and that said throat may be adjustedbackward or forward to operate to the best advantage with the adjustable blade 46. 1

While I have shown and described one form of my invention I reserve all rights to such other forms and modifications as propa throat slide arranged beneath said bridge and slidable longitudinally in said sidemembers,a rack on saidthroat slide, apinion intermeshing with said rack, a shaft extending through the bridge and upon which saidpin- 10n is mounted, a handle rotatably mounted upon the bridge and through which said shaft extends and by means of which said shaft may be rotated, and a nut thread'edupon said shaft and adapted to force the handle against the bridge for securing'said handle against rotation.

V 2. In aplane, a stock provided with an adjustable bit, a bridge fixed to said stock, a throat slide extending beneath said bridge and slidable longitudinally in said stock, rack and pinion means for actuating said throat slide, a shaft mounted in said bridge and upon which the pinion is mounted, a handle through which said shaft extends and whereby it may be rotated, and means threaded upon said shaft and adapted to force the handle against the bridge for securing said handle against rotation. r

3. In a plane, a stock providedwith an adjustable bit, a bridge fixed to said stock, a

journaled in said bridge, means actuated by the rotation of said shaft to operate the throat slide actuating means, a- "handle through which" said shaft extends and'where by it may be rotated, and means threaded upon said shaft and adapted to forcethe handle against the bridge for securing said'han dle against rotation.
